Different types of habitats from which snails were sampled; A–seasonal laterite pool, B–stream, C–river, D–irrigation canal, E–rice field, F–swamp.
Fig 3.
Box and Whisker plots showing the abundance of Bulinus snails by: (A) species and (B) region. The box represents the lower quartile (0.25), the median (0.5) and the upper quartile (0.75); the whiskers depict variability outside the lower and upper quartiles. Outliers are shown as individual points.
Fig 4.
Box and Whisker plots showing the abundance by habitat type of Bulinus snails: (A) B. senegalensis, (B) B. forskalii and (C) B. truncatus. The box represents the lower quartile (0.25), the median (0.5) and the upper quartile (0.75); the whiskers depict variability outside the lower and upper quartiles. Outliers are shown as individual points.
